What literary figures had hidden identities and had bad things happen to them because of this?

I'm writing a paper, part of which that involves hidden identities. I'm looking for any literary figures who had bad things happen to them because of their hidden identities. So far, all I have are Oedipus and King Lauis, Rostam and Sohrab (from the Persian epic poem the Shahnameh), and that's it. There must be at least one Bible story, or a Brothers Grimm tale, or a Shakespeare play...it can be from any culture, even though the ones I listed are pretty Western, except for the Shahnameh.

I'm looking for classic stories, not contemporary ones. Any myths, fairy tales, etc. would be fantastic. Just anything that's pretty well known, even if it's only well-known in another culture. I'd actually really appreciate more Eastern stories (anything from the Ramayana or the Mahabharata or another religion's holy text would be really cool).

By the way, this is very late notice since it's for a paper due Tuesday (April 19th, 2011), but I had been struggling with my thesis, and I just worked it out. Now I just need more examples...

Thanks in advance to anyone who can help me out. And yes, I've tried various search terms in Google, so don't tell me to go Google it.
